Serial No. 411,368.

To all whom itmay concern:

Be it known that l, EDWARD R. GnAMs,

citizen off the United States, residing aty Roseglemin the county of McLean and State of North Dakota, have invented certain new and useful improvements in Mountings for Threshin'g-Machin'es7A of which the following isa specification.

lt is well. known that threshing machines and the like are subject to detrimental vibration andjar when traveling over rough roads, butY they are not. usually provided with springs to compensate. for such vibration since itisI obviously not desirable to have the machine rest on springs while in operation.

The object of this invention is an improved mounting designed tol be interposed between the body portion and the running gear of a threshing machine andwhichis 'arranged to form a resilient orrigid con-nection therebetween according as desired.

With this and other objects in view that will more fully appear as the description proceeds, the invention consists in certain constructions and arrangements of the parts that I shall hereinafter fully describe and then point out the novel features thereof in the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the accompanying drawing, in which:

Figure 1 is a side elevation of my improved spring mounting, with parts in section. Fig. 2 is a detail view in perspective of the extensible brace. Fig. 3 is a detail view in section of the ratchet and pawl; and, Fig. 4 is a similar view of one end of the axle showing a modified form thereof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

Referring to the drawing, A and A. designate respectively the two lower and upper side sills of the main supporting frame of a threshing machine, and B the rear axle to both ends of which my improved mountings are applied.

Each of my improved mountings comprises two guide members 1 secured at their upper ends to a lower sill A and extending downwardly therefrom and spaced from each other as shown to form a channel in which the corresponding end of the rear axle B is mounted for vertlcal movement.y The lower endsy of the guide members 1 travel freely through openings 2 formed the.y ends of a bracket 3 which is secured to the lower side of the axle B and. which extends forwardly and rearwardly therefrom. Two expansion springs 4 are interposed between the respective ends of the bracket 3 and such lower sill A and form a resilienty connection between the axle. and the body portion of the machine, whereby theV axle is permitted to ride upwardly in the channel when it receives a jolt, and is thus prevented front transmitting the latter to the body portion.

An extensible brace 5 is secured to the axle. B and comprises. a lower actuating screw 6 pivotally mounted at its lower end between two ears 7 provided on. the upper side of the axle B, an oppositely threaded upper actuating screw 8, and` a, turnbuckle 9 having4 its 75 oppositely threaded andin engagement.

with the espe'tive actuating 'screws 6' and 8. 'lhe upper end of the screw 8 is perferably attened as indicated at 10 and normally travels freely through a bearing strap 11 secured to the adjacent upper sill A1, a screw clamp 12 being mounted in said bearing and being adapted to hold the flattened end 10 rigidly in the bearing and to the body portion. 'l he turnbuckle 9 is provided with a ratchet 13 and a handle 14 that has a reversible pawl 15 operatively engaging with the said ratchet and rendering the handle capable of rotating the turnbuckle in either direction, which movement obviously results in the extension or contraction of the brace.

In the practical use of my improved mountings when it is desired to dispense with the use of the springs and to establish a rigid connection between the body portion and the axle, the braces are rigidly secured at their upper ends to the body portion and are extended, which movement obviously raises the body'porti on and thus relieves the springs of the weight thereof and of any tension.

'lhe above operation is reversed to restablish the spring connection between the body portion and the running gear. lt will be further noted that the extensible braces may be employed to quickly and easily adjust the body portion to level it when the threshing machine is operating on uneven ground.

TJvhile my improved mounting has been described in connection with threshing machines, it is to be understood that it is applicable to vehicles generally.

It is to be understood, that if desired the l the body portion, a brace rigidly secured at guide members 1 may travel in vertical channels 16 formed at the opposite sides of the axle as clearly shown in Fig. 4, instead of in openings in the ends ofthe bracket 3.

Having thus described the invention, what I claim is:

1. 'ihe combination with Vthe axle and body portion of a vehicle, of means for establishing a resilient connection therebetween, an extensible brace secured to one of said parts and having a sliding connection at its other end with the other part, and means for rigidly connecting said last named end of the brace to the corresponding part, whereby to hold the resilient means inoperative.

2. 'l he combination with the axle and body portieri of a vehicle, of springs interposed therebetween and arranged to support the body portion, a brace rigidly secured at one end to one of said parts and having a sliding connection at its other end with the other part, means for rigidly connecting said other end of the brace to the corresponding part, and means for extending the brace, as and for the purpose specified.

3. rIhe combination with the axle and body portion of a vehicle, of springs interone end to one of said parts and having a sliding connection at its other end with the other part, means for rigidly connecting said last named end of the brace to the corresponding part, said brace being constructed in sections, and a turn buckle adjustably connecting said sections, as and for the purpose speci ed.

4. rlhe combination with the axle and` body portion of a vehicle, of means for establishing a resilient connection therebetween, a brace rigidly secured at one end to one of said parts and having a sliding connection at its other end with the other part, means for rigidly connecting the last named end of the brace and the corresponding part, said brace being constructed in sections, a turn buckle adjustably connecting said sections, and a handle mounted upon the turn buckle and having a ratchet and pawl connection therewith, as and for the purpose specified.

In testimony whereof I afi-ix my signature in presence of two witnesses.

EDWARD R. GRAMS.
